Application led December 28, 1914. Serial No. 879,366.

To all whom t may concern Be it known that I, ALFRED AYRD MELLOR, asubject of the King of Great Britain, and resident of 400 St. J amesstreet, in the city of Montreal, Province of Quebec, in the Do-` minionof Canada, have invented certain new and useful Improvements in Attachments for Unloading Apparatus, as described in the followingspecification, which is a full, clear, and eXact description of thesame.

The invention relates to improvements in attachments for unloadingapparatus as described in the present specification and illustrated inthe accompanying drawings that form part of the same. Y

The invention consists essentially in the novel means employed fordirecting the material from a vehicle and depositing it as desiredduring unloading operations.

rThe objects of the invention are to devise an apparatus that willfacilitate the discharge of a load from vehicles, particularly railwaycars containing` loose material, and at the same time avoid anyinterference with the means of unloading, to effect a reduction inexpense of labor in such operations, to lessen the period oit' timerequired for distributing the material deposited and generally toprovide an apparatus of a durable nature that will not be in the wayduring the ordinary travel of the vehicle and which will be simple tooperate and cheap to manufacture.

ln the drawings, Figure 1 is a vertical sectional view along the center-line vof unloading plow showing frame applied thereon to which theimproved device is iiXed. Fig. 2 is a side elevation of unloading plowshowing the invention aiiixed thereto. Fig. 3 is a cross section on line3 3 showing plow and the invention in elevation. Fig. 4 is a half planview of the invention and half sectional view on line 4 4 of Fig 8.

Like numerals of reference indicate corresponding parts in each ligure.

rThe numeral 1 indicates a railway car of the type used for ballast,loose earth, sand or like material, such cars being used largely inrailway construction, the various cars of a train being connected attheir open ends lby plates or gangways, so that there is anuninterrupted passage from one end of the train to the other. After eachcar is loaded and the train hauled to its destination, the material isdeposited by an unloading plow of anysuitable type and which is drawnfrom one end of the train to the other, subsequent of course to theopening of the side doors in the walls of said cars. This practice hasbeen carried on for many years and in all its details is well known tothose versed in the art. n

There are single and double plows, that is to say, plows for unloadingone side ot' the car and plows for unloading at both sidessimultaneously. The double plow is illustrated in the accompanyingdrawings, though this invention is equally etlicient as an attachment toa single plow, the dierence being that one flash board is used insteadof two. The flash boards or plates are supported by frames from the plowand in the drawing the numeral 2 indicates the two rearor main moldboards while 8 indicates the mold boards of a pilot plow, and as theseparts of theplow are those that most intimately concern this invention,the plow frame and braces will not be described herein, it beingsuliicient to say that these mold boards are' properly and rigidly heldby frames in such a manner that they can be drawn lfrom one end of thetrain to the other and clear the earth, sand, gravel or other materialfrom the sides of the cars through the side door ways.

The flash boards or plates 4 are pivotally supported at the lower endsof the connecting bars 5, the latter being in pairs and preferably inangle form. The said bars 5 are joined to the flash boards 4 by means ofthe angle bars 6 extending across the boards 4 at intervals. v Y

The adjusting bars 7 are pivotally secured at the inner edge of theflash boards 4 and each has a row of holes 8 therethrough. The said bars7 extend outwardly between the members of each pair of bars 5, though itis not necessary to have an adjusting bar for every support, still it ispreferable.

The adjusting bars 7 are held in the desired position between the bars 5by the pins 9, this position being changed according to the material andthe work at the place of the discharge. rl`he connecting bars 5 at their`upper ends are pivotally joined to the brackets 1 0, said bracketsbeing of plate form andhaving the vertical rows of holes 11 and 12, bothextending from the pivot 13 at the lower end joining the bars to thebrackets so that the Hash boards 4 may be `further adjusted in theirpositions by the use of one or other of said rows of holes as sov thecase may be, and in the lower and working position of the flash boards,pins are inserted through corresponding holes in the connecting bars 5vinto and through the bracket holes, thus holding the bars pei'- fectlyrigid in respect to the brackets so long as the unloading opera-tioncontinues.

The brackets 10 are rigidly secured to the l the pilot mold boards 3 andtoward its rear from tbe main nn'old boards 2. The uprigbts 19 arerigidly secured to the pilot niold boards 3 and support the cross bar20, to whieh tbe forward cross bar of the pivoted frame is 'secured bythe pivot 21.

The nprights 22, 23 and 24 are rigidly secured to the main mold boards2`and each pair, of said uprights support corresponding cross bars, thecenterP cross bar 25 being joined to a cross beam 17 'or :tbe upperl`frame by a pivot '26, the rear pivot joint being reinforced by thediagonal braces 27.Y The posts 28 are secured to tbe cross beams 17 bythe angle brackets -y 29 and from their upper ends carry the block andtackle 30 forraising and lowering the arins 14, con-g sequently theconnecting bars 5, brackets 10 and flash boards 4 are lifted andlower'edby said tackle, saidV connecting bars 5V being first relieved fromtheir" pin connection with the brackets 10 and allowed to on theirpivotal connection with said brackets thus in their upper position theflash boards will rest on the cross beams '17,- which is.

plainly shown in Fig. 3, the arms le being in a vertical position.y Thepositions of the brackets 10 change conse'qiient upon the change of theposition of the said arns 14, towhich they are rigidly attaohed and thepositions of tbe connecting bars 5 still remain vertical and carrythe'fl'ash boards e at their lower ends onthe cross beanis 17. The partswill all fall into place' very nat'- ur'ally on lowering the, arms 111,and connecting bars 5 to the brackets 10, to which they are pinnedthrough one or other of the vertical rows of holes. The flash boards arethen adjusted by means of the bars 7 and pinned to the required slant. AAs the plow moves forward the meld boards of the plow throw the materialoff the side of the car and this material is guided bythe flash boardsaway troni the track and the line of travel of the vehicle.,

`Thedevic'e is 'of inestir'nable value in unt loading work and i`s`intimately associated with. the work of an unloadingy plow, though other'uses may be found for it, also the parts may be arranged andconstructed dinerently so long as the main elements re.- main as setforth in the claims for novelty following. v
